Embodiment Construction

[0031] According to Figure 1, the control structure for mounting on a toaster (not shown) has a microcontroller 1 (schematically shown) with an internal timer 7 and a delay timer 3.

[0032] There is also a roasting process stop switch 11 and a roasting start switch 13 at the input of the microcontroller of FIG. 1 . The former is used to interrupt the toasting process at any moment and send out the bread. The latter can be a button operated by the user, or a switch activated when the bread supporting carriage is in a low position.

[0033] According to the preferred embodiment, an output amplifier unit 14 is used to control a process relay module 12 of the heating element 10, an electromagnet 15 maintains the bread supporting carriage 16 in a low position, and this electromagnet can also communicate with said amplifier. The units are connected or, as in this embodiment, directly controlled by the microcontroller 1 .

Abstract

The invention concerns a method for determining the thermal condition of a heat chamber of a toaster wherein extend grilling and / or heating means, said toaster having in particular means for triggering a grilling or heating cycle and means for adjusting the desired degree of grilling. The invention is characterised in that it consists in: measuring, at two different times (t1) and (t2) after triggering the grilling or heating cycle, respective values (A1) then (A2) of a thermally variable capacitor (C) or a quantity representative of said value, said capacitor (C) being subjected to the influence of the grilling and / or heating means; calculating the ratio (r) of the two measurements (A1, A2) produced so as to determine the thermal condition of the heat chamber at the triggering time of the grilling or heating cycle.

Description

technical field [0001] The invention relates to the field of toasters, in particular to a toaster controlled by a microcontroller. Background technique [0002] The invention is particularly concerned with the use of the initial temperature of the heating chamber to compensate for the baking time of the bread, such compensation being used in microprocessor controlled toasters. In this toaster, the toasting time range has been preselected according to values ​​stored in the microcontroller, which are adjusted during use according to the temperature prevailing in the baking chamber at the beginning of the toasting process. [0003] As in document US 5 128 521 the temperature in the heating chamber can be determined by measuring the time interval between two consecutive uses of the toaster. However, this solution does not have a real concept of the temperature in the heating room, and the physical disconnection of the toaster erases all data on this parameter. [0004] Docume...
